POLE.

Specification 02 Letters Patent.

Application filed August 8, 1917. Serial No. 185,127.

To all whom it may concern:

Be it known that I OnvILLr. M. Knox, a citizen of the United States,residing at Knoxboro, in the county of Oneida and State of New York,have invented certain new and useful Improvements in Poles, of which thefollowing is a specification, reference being bad to the accompanyingdraw- .ings.

This invention relates to certain improvements in poles and has relationmore particularly to a device of this general character especiallydesigned and adapted for use in connection with telegraph or telephonelines and it is an object of the invention to provide a. novel andimproved device of this general character formed of metal, preferablyrolled steel and which has reinforcing sections co-acting with theopposite faces thereof in order that the pole may possess a maximum ofstrength.

It is also an object of the invention to pro vide a novel and improveddevice of this general character wherein the lower portion thereof hasits opposite faces provided with casings of cast iron in order toprotect the lower portion of the pole when embedded within the groundfrom corrodiug.

The invention consists in the details of construction and in thearrangement of the several parts of my improved pole wherein certainii'nporta-nt advantages are attained and the device rendered simpler,less expensive and otherwise more convenient and ad vantagcous for use,as will be hereinafter more fully set forth.

The novel features of my invention will I hereinafter be definitelyclaimed.

In order that my invention may be the better understood I will nowproceed to dcscribe the same with reference to the accompanying drawingswherein Figure 1 is a view in perspective illustrating a poleconstructed in accordance With an embodiment of my invention; and

Fig. 2 is a sectional view taken longitudinally of the pole, theopposite ends of the pole being broken away.

As disclosed in the accompanying drawings 1 denotes the body of myimproved pole consisting of an elongated member of predetermineddimensions and which is substantially L-shapcd in cross section. Thebody 1 is preferably formed of rolled steel.

Secured to the opposite faces of the body L are the reinforcing plates 2and 3 extending from the lower end of the body 1 to a predeterminedpoint inwardly of the opposite end thereof. Each of the plates 2 and 3are successively of shorter lengths and are se cured to the body 1through the medium of the rivets 4: or the like. It is to be noted thatalternate plates 2 and 3 are substantially equally shortcnedso that therequisite and proportionate strengthening or reinforcing of the body 1is retained. The lower portion of the pole has secured to the outerfaces of the lower plates 2 and 3 the cast iron plates 5. The plates 5are of such a length as to incase the portion of the pole which isembedded or set within the ground so that the body 1 and plates 2 and 3which are also preferably made of steel, are effectively protected fromcorroding so that the life of the pole is materially prolonged. Thelower end portions of the plates 5 are flush with the lower end of thebody 1 and the plates 2 and 3 and the upper ends of the plates 5 aresubstantially flush. It is also to be noted that the flanges of theplates 2, 3 and 5 are of such width as to extend entirely across theflanges of the body 1.

Bolted as at 6 or otherwisesecured to the upper end portion is a crossbar 7 to which the lines are adapted to be engaged. Also suitablysecured to the pole at predetermined points longitudinally thereof arethe strips 8 extending beyond opposite sides thereof and which affordmeans whereby a lineman may readily ascend or descend the pole.

rom the foregoing description, it is thought to be obvious that a poleconstructed in accordance with my invention is particu -larly welladapted for use by reason of the convenience and facility with which itmay be assembled and operated and it will also be obvious that myinvention is susceptible of some change and modification withoutmaterially departing from the principle and spirit thereof and for thisreason I do not wish to be understood as limiting myself to the precisearrangement and formation of the several parts herein shown in carryingout my invention in practice except as hereinafter claimed.

I claim:

1. A pole comprising an elongated membcr angular in cross section,imposed reinforcing members angular in cross section and secured to theopposite faces of the. pole and to each other and extending from thelower end. of the pole, the upper ends of the Patented June 25, 1918.

l plates terminating an equal distance below the upper. ends ofalternate plates, the flanges of the plates being of a width to ex- Itend entirely across the flanges of the body.

f2. A .pole comprising an elongated'memher angular 1n cross section, andlmposed reinforcing members angular 1n CIOSSYSGCUOII and secured to theopposite faces of the pole and to each'other and extending from the thebody and plates being formed of steel 15 and the casings of cast ironsecured to the outer faces of the lower of thefirst named plates, saidcast iron plates being angular in cross section with the flanges thereofof a width to extend entirely across the flanges 2c of the body.

In testimony whereof I hereunto aflix my signature in the presence oftwo witnesses.
